160 Tstat
And why do you say it's a zero value mod jimmy? It's not gonna make you produce more power, but isn't it good to keep the engine a little cooler for the sake of the engine? Especially if you drag it or drive it hard a lot. My understanding is the stock thermostats are high to keep the engine hotter so the catalytic converters work better, but in the case of many of us who run catless it's better to have the engine run around 180 degrees instead of 200.

Although my car rarely pinged, it never pings with the t-stat/fan mod. It runs better and cooler.
I can't say I gained any horsepower (it did feel better) but overall it's a good mod to do.
I would suggest everybody buy a spare PCM off ebay, they're like 80-90 bucks. Send it to PCM For Less to get your tunes and updates. This way, you don't have any downtime and you can still use your car.

need it, and no different when things get hot, helps any.
Say it with me, now... thermostat... sets... minimum...
temperature. Not maximum.
HOWEVER, since I've done the mod, my temp gauge went from always sitting at 210 to always sitting a nice bunch below it. Using a TechII, I see my real running engine temperature runs 180 to 185. We've had some pretty hot days here in NYC this summer, in the 90's a lot. That gauge has sat just nice below the 210 mark meaning 180-185 even sitting in traffic with the AC on.
My temps have never gone over this since the mod.
